Classic treble
The classic treble response provides a much steeper gradient between EQ’d and
non-EQ’d frequency areas, as made famous by previous Midas consoles like the XL4.
This provides better differentiation and minimal phase shift, but there is some
undershoot error, that is, when boosting the treble, the mids are slightly cut and vice
versa. This is the best all round EQ and especially effective when microphones are
covering multiple sources.
Bright treble
The bright treble response provides a slightly steeper gradient than the classic and it is
uniquely shaped to provide minimum harmonic disruption to the EQ’d material. As for
the classic EQ, this provides better differentiation and minimal phase shift, but now
there is no undershoot error corrupting the mids. This is best used on single source
material and especially good for acoustic performances.
Warm bass
The warm bass response provides a very gentle gradient between EQ’d and non-EQ’d
frequency areas. This produces the absolute minimum of phase shift, but does not
provide much differentiation, thus frequencies outside the area of interest are often
unintentionally EQ’d. This is best used to provide gentle shaping of pre mixed material.
Classic bass
The classic bass response provides a much steeper gradient between EQ’d and
non-EQ’d frequency areas and is modelled on the XL4. This provides better
differentiation and minimal phase shift, but there is some undershoot error, that is,
when boosting the bass, the mids are slightly cut and vice versa. This is often desirable
on bass EQ and it is the best all round, general purpose EQ curvature.
Deep bass
The deep bass response provides a slightly steeper gradient than the classic and it is
uniquely shaped to provide minimum harmonic disruption to the EQ’d material. As for
the classic EQ, this provides better differentiation and minimal phase shift, but there is
no undershoot error. Powerful boost/cut can be used that still sounds very natural and
does not corrupt the mids. This is best used on single source material.
PRO2 output channel EQ modes
This section aims to provide an understanding of the output channel EQ modes
contained within the PRO2 control centre.
Basic specification
The PRO2 output EQ comprises six bands strategically positioned at certain frequencies
ranging from the low end (bass) to the high (treble) of the frequency band. The default
operation for all six sections is full parametric sweep (peak), with the following controls:
• Gain: continuous adjustment of boost and cut from + 16dB to - 16dB.
• Width: continuous adjustment of bandwidth from 0.1 to 3.0 octaves.
• Frequency: continuous adjustment of the frequency range that the band EQ acts on
from 16Hz to 25kHz.
Band 1 can be switched from parametric to any of three shelving modes: warm; high
pass filter 6dB; and high pass filter 12dB.
